The experiment was conducted to determine the effect of dietary substitution of durian seed starch for broken rice on productive performance in 120 broilers at the age 0 – 35 days old. Completely Randomized Design (CRD) was used in this experiment which was divided into 3 treatments (control, substitution of durian seed starch for broken rice at 2 and 4 percentage in ration) with 4 replications for each treatment and 10 birds for each replication. All treatments were fed with layer diets containing the same level of energy and protein. The results showed that at 7 - 35 days substitution of durian seed starch, 4 percentage treatment had average body weight gained higher than control group at significant difference (P<0.05) but no difference in 2 percentage substitution group. Moreover, 2 and 4 percentage substitution groups had no effect on productive performance in broiler for average body weight gained (at 7 – 21 and 21 - 35 days), average feed intake, feed conversion ratio and survival rate throughout the experiment period (7 - 35 days).
